Outcomes of patients with nonepileptic transient neurologic symptoms after subdural hematoma evacuation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients undergoing a subdural hematoma (SDH) evacuation can experience transient neurological symptoms (TNS) postoperatively. Electroencephalography (EEG) is used to rule out seizures. We aim to characterize patients with TNS and negative epileptiform activity on EEG and compare them to those with positive epileptiform EEG findings.
methodsWe performed a retrospective study of adult patients who underwent EEG for evaluation of TNS after undergoing SDH evacuation. Patients were stratified based on SDH type (acute and non-acute) and whether or not their EEG demonstrated positive epileptiform activity. A multivariate analysis was performed to identify predictors of negative EEG findings.
resultsOne hundred twenty-nine SDH patients were included (45 (34.9%) acute; 84 (65.1%) non-acute). Overall, 45 (24 acute and 21 non-acute SDH patients) had positive epileptiform EEG findings, and 84 (21 acute and 63 non-acute SDH patients) had a negative EEG. Acute and non-acute SDH patients with positive EEG findings were more likely to suffer from greater than five episodes of TNS, impaired awareness, and motor symptoms, while the negative EEG group was more likely to suffer from negative symptoms. Non-acute SDH patients with positive EEG had longer mean ICU stays (14.6 vs. 7.2; p = 0.005). Both acute and non-acute SDH-positive EEG patients had worse disposition upon discharge (p < 0.05), worse modified Rankin score at discharge (p < 0.05), and 3-month follow-up (p < 0.05) and were more likely to be discharged on more than one antiepileptic drug (p < 0.001).
conclusionPostoperative acute and non-acute SDH patients with TNS and negative EEG results are likely to have a favorable clinical picture. This distinction is therapeutically and prognostically important as these patients may not respond to typical antiepileptic drugs and they have better functional outcomes.
